Which Checks Does Email Validator Perform?

DeBounce uses a multi-layer checking process, with every single email going through all of these testing and cleaning steps:

  • DNS validation, including MX record lookup
  • Disposable email address detection
  • Misspelled domain detection to prevent Typosquatting
  • Syntax verification (IETF/RFC standard conformance)
  • Temporary unavailability detection
  • Mailbox existence checking
  • Catch-All testing
  • Greylisting detection
  • SMTP connection and availability checking

How to Use DeBounce API


For applications that are in need of real time email address verification (such as account registration workflows) our real time lookup API is the perfect tool for the job. It consists of a single endpoint and requires very little to make use of in a production application. For simplicity and ease of use, we've decided to make lookups available on the GET method.

📎 Lookup Example



To perform a single lookup on our real-time email verification endpoint, perform a GET request on the following URL:

https://api.debounce.io/v1/?api=API_KEY&email=EMAIL_ADDRESS
API_KEY: Your application API key at DeBounce.
EMAIL_ADDRESS: The email address you want to verify.

Each response, includes email validation response. Moreover, your DeBounce remaining balance is included to let you know how many calls you can perform before your credits end.

📎 Getting your Account Balance



In order to get your account balance, you need to have at least one API. Use one of them to call following API endpoint:

https://api.debounce.io/v1/?api=API_KEY&action=balance
API_KEY: Your application API key at DeBounce.

Response is the number of credits are available in your DeBounce account.
